DEODORIZING AND INSECTICIDE ATTACHMENT FOR VQCUUM CLEANERS 'Filed Nov. 24, 1931 2 Sheets-Sheet 2 Patented May 30, 1933 UNITED STATES PATENT orr 'lca EDWARD H. BEBNDBEN AND JOHN L. KELLY; 0! 8'1. LOUIS, IIBSOUEI DEODOBIZING AND IHSEOTICIDE ATTACHIENT FOR -'VACUUI CLEANERS Application ma November 24, 1031. Serial No. $7,137.

This invention relates to devices for distributing deodorizin and insect destroying substances and pertamsparticularly to a device designed to be used in association with a blower element.

The primary object of the present invention is to provide a device for attachment to a vacuum cleaner which is adapted to contain a deodorizing and insect destroying chemical which is drawn therefrom by the suction mechanism of the vacuum cleaner and discharged through the vacuum cleaner chine at the point normally engaged by the dirt receiving bag of the machine.

A further object of the invention is to provide an attachment for the purpose described, which when used with a particular type of deodorant and insect destroyer which occurs in easily broken and volatile crystals, will break up these crystals into a fine state so that they .will more rapidly volatilize and be more effective in killing insects and in deodorizing the air into which discharged.

A still further object of the invention is to provide a device for the purpose described which may be easily and quickly applied to or removed from a vacuum cleaner.

The invention will be best. understood from a consideration of the following de- I tailed description taken in connection with .the accompanying drawings forming part of this specification, with the understanding however, that the invention is not confin to any strictconformity with the showing of the drawings but may be changed or m ified so long as such changes or modifications mark no material departure from the salient features of the invention as expressed in the appended claims.

In the drawings Figure 1 is a dia rammatic view of a vacuum cleaning mac ine in side elevation showing the device embodying the present invention applied thereto;

Figure 2 is a. vertical longitudinal sectional view through the insecticide holder of the device;

Figure 3 is a sectional view taken on the line 3-3 of Figure 2;

Figure 4 is a sectional view taken on the line 4-4 of Figure 2;

Figure 5 is a sectional view taken on the line 55 of Figure 2;

Figure 6 is a sectional view taken on the line 6-6 of Figure 1.

Referring now more particularly to the drawin wherein like numerals of reference in icate corresponding parts throughout the several views, the numeral 1 indicates generally a vacuum cleaner machine of the type commonly used in households and adapted to be moved about from place to place upon the supporting rollers 2.- The fan casing of the present machine is indicated by the numeral 3 and the inlet thereto is throu h the nozzle 4, to which is normally attac ed the suction or pick-up nozzle (not shown) of the machine. Theoutlet,

nozzle of the blower or fan casin 3 is indicated by the numeral 5 and this nozzle, as well as the nozzle 4, upon the majority of machines of this character, is provided with lugs 6 for engagement in slots 7 formed in the inner wall of a collar 8 to whlch the flexible hose 9, which is sup lied with such machines, is connected. rdinarily the outlet nozzle 5 of the fan casing has attached thereto a dirt receiving container or bag but for the use of the attachment embodying the present invention this bag is removed and the hose is coupled with this nozzle, as will be hereinafter more fully described. Also, for the use of the present attachment the pick-up nozzle normally connected with the inlet nozzle 4 of the fan housing, is removed and a part of the prescasing 13 preferably of cylindrical formation, one end of which will hereinafter be'referred to as the mner end, is formed to provide the collar 14 which receives the nozzle 4, this collar being supplied with the necessary slots for the rece tion of the lugs on the collar to hold t e cylinder in the position shown.

Inwardly of the inner end of the cylinder 13, preferably about one inch therefrom when the cy inder is approximately seven inches long, is a screen wire artition which is spaced at its lower ge'from the lower part of the cylinder, thus leaving the unscreened entrance opening;l 16. At one side of the opening 16 the c nder has secured to the wall thereof i e elements 17 and disposed between ta screen and these guide elements is a ate plate 18 which ma be moved upwardly ietween the guides an the screen to uncover the opening 16.

The movement of this gate 18 is controlled by a screw 19 which asses downwardly through. the top of the cy rider and engages a nut 20 carried by the gate. This screw 19 ma be swivelly mounted in the wall of the cy 'nder so that upon rotatin the same through the medium of the he 21 upon the outer end thereot the nut 20 will he caused to ride up thereon and at the same time raise the gate.

Adjacent the other or outer end ofthe c linder 13 is an air inlet control disk 22, t e upper half of which is im eriorete as indicated at 23, while the other elf thereof is formed of-wire screen as indicated at 2%. This screen may be readily removed from the end or the cylinder to permit or the introduction of a suitable deodorining and insecticidal chemical of any suitable character, the use of the chemical known as paradichlorhenzene.

When the device is not in use the outer end thereof may he closed by the cap 25 which has a flange portion 26 which threadabl engages about the end of the cylinder.

'lhe e ement 11 is in the form of a cylinder which has a collar 27 at one end formed to couple onto the outlet nozzle 5 of the blower casing and its other end 28 is "formed for extension into the collar 8 to which the hose 9 is attached. This end- &8 is provided with lu similar to lugs 6 on the nozzles d and 5, a1 engagement in the slots of the collar 8. Within this cylindrical element 11, which as shown is designed to be interposed between the hose 9 and the discharge nozzle 5, are two partitions 29 of relatively fine mesh screen wire.

' The element 12 is also in the form of a cylinder and this is of the same or constant diameter throughout and is intended to snugly engage in the hose 9 in the manner shown. v

This cylinder element 12 also has a pair oi screen 'fivire partitions therein like the cylinder element 11 these screen wire partitions b the numerals 30.

being indica 1 In the use of t e present attachment for the killing and controlling of moth infestation in furniture, clothes, etc. the proper dri; chemicals are placed in the container 0 'nder 13 by removing the cap 25. With t e elements 11 and 12 in the positions illustrated and the gate element 18 raised to the pro or hei ht to permit the desired amount'o .crys to be sucked from the container for dischar e through the hose 9 the machine is sta and the hose directed as desired for dischargin the chemical into furniture, clothes or e sewhere. As the chemicals are drawn from the container cylinder 13 they will be forced throu h the fine wire mesh partitions of the cylinders 11 and 12 and broken up into a fine powder so that the volatilization thereof can take place rapidly. The major portion of the chemical is therefore dischar ed from the hose 9 as a gas while some of t e unvolatilized powder will be discharged also.

For the eradication of roaches and other insect pests and for deodorizing, it is not necessary these are only intended for use in association with chemicals which come in crystal form such as the chemical previously referred to.
